Pre-germinated brown rice reduced both blood glucose concentration and body weight in Vietnamese women with impaired glucose tolerance.

We have reported that newly diagnosed type 2 diabetes mellitus (DM) patients in Vietnam have a low body mass index (BMI) of around 23 and that the major factor for this is high white rice (WR) intake. Brown rice (BR) is known to be beneficial in the control of blood glucose levels; however, it has the property of unpleasant palatability. Pre-germinated brown rice (PGBR) is slightly germinated by soaking BR in water as this reduces the hardness of BR and makes it easier to eat.

Effects of pre-germinated brown rice on blood glucose and lipid levels in free-living patients with impaired fasting glucose or type 2 diabetes.

White rice (WR) is made by polishing brown rice (BR) and has lost various nutrients; however, most people prefer it to BR, maybe because of the hardness of BR. Pre-germinated brown rice (PGBR) improves the problem of BR. It is made by soaking BR kernels in water to germinate and becomes softer than BR.

Effects of pre-germinated brown rice on depression-like behavior in mice.

We investigated the antidepressant-like effects of pre-germinated brown rice (PGBR) and polished rice (PR) pellets, respectively, in comparison with control (AIN-93G) pellets in the forced swimming test and the learned helplessness paradigm in mice. Mice were fed respective pellets for 30 days. The immobility time on the 2nd day of the forced swimming test was shorter in mice fed with PR or PGBR pellets than in mice fed with control pellets.

Hypocholesterolemic action of pre-germinated brown rice in hepatoma-bearing rats.

The effect of pre-germinated brown rice (PGBR) on cholesterol metabolism was studied in Donryu rats subcutaneously implanted with the ascites hepatoma cell line AH109A and compared with that of white rice (WR). The effect of brown rice (BR), the source of PGBR, was also studied. Hepatoma-bearing rats fed a WR diet exhibited hypercholesterolemia compared with normal rats fed the same diet.

Postprandial blood glucose and insulin responses to pre-germinated brown rice in healthy subjects.

Effects of pre-germinated brown rice (PGBR) on postprandial blood glucose and insulin concentrations were compared with brown rice (BR) and white rice (WR) in two studies. In the first study, we investigated the time course of postprandial blood glucose and insulin concentrations after ingesting 25% (W/V) glucose solution, PGBR, BR or WR in 19 healthy young subjects. In the second study, dose-dependent effect of PGBR on the time course of postprandial blood glucose concentrations was compared among 4 different mixtures of PGBR and WR in 13 healthy young subjects.

Effects of pre-germinated brown rice on beta-amyloid protein-induced learning and memory deficits in mice.

We evaluated the effects of pre-germinated brown rice (hatsuga genmai, PGR) on learning and memory and compared them with those of polished rice or cornstarch. In mice that were fed pellets of polished rice or PGR for two weeks, the learning ability in the Morris water maze test was significantly enhanced compared with mice that were fed cornstarch pellets. In the Y-maze test, the intake of food pellets for two weeks failed to affect spontaneous alternation behavior.
